Abstract—A single-input double-output converter, which receives a DC voltage and supplies an AC and a DC load, is introduced in this paper. The topology is based on merging a half-bridge DC/AC inverter with a conventional DC/DC boost converter. The DC load supplied in one of the output terminals experiences an increased voltage level compared to that of the input voltage. As for the AC load, the peak amplitude of the voltage is no more limited to half of the input DC voltage and can be controlled to be a larger value. A lookup table based control method using selective harmonic elimination technique is developed to reach the intended output DC and AC voltage levels. Using less number of elements and providing step-up functionality for AC output are the most prominent advantages of the converter. The proposed converter can be used in micro-grids, which comprise numerous types of DC sources and AC/DC consumers. The operation of the DC-AC/DC converter is examined using simulations under different conditions and scenarios.
